I v p .10 Claims. This inventionrelates to a method or process for manufacturing beaded cord that involves a substantially continuous process at relatively high speed and that produces a product almost position to" the glue spots, finishing the beads thus formed-under hot temperature and pass ing the same thru a quick freezing chamber, then dipping the same in a prime coating solution to close the pores or crevices and preserving the shape asraw material stock for a period of seasoning, after which the beaded cord may be colored or provided with a metallic finishing coating as desired.

. The invention comprises the novel .process hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates an apparatus for carrying out this invention and in which similar reference numerals refer to similar features in the different views:

Fig. l is a side elevational view shown somewhat in diagrammatic form of an apparatus for carrying out this invention.

Fig. 2 is asectional view taken upon the line 2-4 of Fig.1 looking in the direction of the arrows and showing parts in elevation. a

Fig. 3 is a sectional view taken substantially upon the line 33 of Fig. 1 looking in the direction of the arrows.

Fig. 4 is a diagrammatic view of a coloring unit forming a part of the apparatus.

In referring to the drawing, there is shown in Fig. 1, a reel or drum 5 which supports a supply of cord upon which it is desired to place beads. This cord which is designated Sis passed between a pair of guide rolls '|T supported on a bracket 8 rising from a. glue tank 9. A rotatable shaft I0 is supported in the wall of the glue tank andthis shaft carries a gluing arm within the tank. Rotation of the shaft will rotate the arm.

.' it causing the same to dip into the glue in the tank and deposit such glue as adheres to its tip against the cord when the'ar'm rises sufllciently.

Asthe cord travels substantially continuously, 55

while the arm ll strikes-the cord intermittently, the glue spots which are represented by the reference I! will occur in uniform-spaced relation. The glue spots l2 which are made by a fast drying glue are subjected to the drying influence'of a rotary fan It which conveniently positioned adjacent the path of travel of the cord for th purpose of expediting the drying of the glue spots. The cord next passes between a pair of co-operating rolls It and I5 which are provided respectively with semi-spherical cavities lid and 15a. in their peripheries so spaced in each roll that a cavity in one will register with a cavity in the other roll at the point of tangency oftherolls, that is at the point where they come closest together. With reference to Fig. 3, it will be noted that the rolls M and I5 are provided respectively with off-set rim portions. Nb and lip in which the cavities are formed.

Contacting the inner surface of each ofi-set rim of the rolls, there is an air inlet member I6 which is provided with an air inlet duct I! to which air under pressure may be. periodically supplied from an air hose l8. An air passage is extends from each duct II to the off-set rim Mb or I5b for periodic registration with air ducts 20 in the off-set rims which ducts communicate with the cavities therein. The members l5 are provided with curved surfaces to correspond with the inner surfaces of the rims and they are positioned centrically of the common diameter of the rolls that passes thru the point of tangency of the rolls. As. airesult, when a pair of cavities come into registration, their air ducts 20 will register with the air ducts l8 whereby air under pressure may be supplied or forced into the cavities to release the half beads as will later more fully appear.

A suitable composition in the form of a viscous, plastic and somewhat liquid material is adapted to be supplied to the cavities in the rolls l4 and I5. As a matter of illustration, there is shown a tank 2| adjacent the roll I! for containing the plastic composition. A pair of co-operating material transfer rolls 22, one engaging roll II, are supported byjhe tank 2! for transferring the material therefrom to the cavities in the 'roll It. For this purpose, the rolls 22 may be brush rolls or the like or have suitable conveyin surfaces. They may be rotated by any suitable means.

At the bottom of the roll l5, there is a second tank 23 for containing a'similar plastic composibrush roll 24 or the like supported in the tank 23 so as to dip into the viscous composition therein. Excess material may be scraped from the rolls l4 and I5 and the cavities cleaned by suitable brushes 25. In addition, scrapers 26 bearing against the rolls may be used if desired for cleansing the peripheries of therolls.

The beaded string-like member next passes between a pair of semi-cylindrical rolls 21 which have threaded peripheries upon their arcuate surfaces of such a pitch as to cause a speed equal to the speed of travel of the cord. As the beaded cord passes between these half moon rolls, any fins that may have been formed during the ap plication of the beads are removed and the beads are more or less bumishedi These rolls are adapted to be heated by the gas Jets 28, one adjacent each roll. These rolls might be termed finishing rolls for the beads.

The beaded cord or string-like beaded member then passes thru a freezing or refrigeration tank 29 containing a quick freezing mixture or chamber.

From the refrigerating tank 29, the beaded cord passes over a guide roll 30 and into a dipping tank 3i containing a prime coating solution which closes the pores of the beads and preserves the shape. The beaded cord then passes from the tank over another guide roll 32 and onto a reel or drum 33 for a period of seasoning. This product may be termed the raw stock which, after seasoning, is ready for finishing according to csired specifications.

After a suitable period of seasoning and when it is desired to utilize or dispose of part or all of the raw stock, it may be finished as to color or coating by passing the same thru the finishing or coating mechanism shown in Fig. 4 which will have been supplied with the proper coloring solution or spray. To accomplish this, the beaded cord or string-like member from the storage roll 33 is passed over a guide roll 34 supported above the dipping tank 35 from which roll, the beaded cord is allowed to dip into the tank for receiving a dress color of some depth and from which it emerges over another guide roll 36.

From the .guide roll 36, the colored beaded cord is passed to another dipping tank 4i which may contain a solution for a smooth lacquer finish, a pear cellulose finish or a crackle finish. In passing between these tanks, the beaded cord is subjected to the drying influence of a rotary it is dipped into a clear lacquer which is adapted to be supplied to the tankfor such a purpose. The finally finished beaded cord may then be dried by the fan 45 and stored upon the reel 44.

It will be evident that the process herein set forth, after started, will preform the different operations simultaneously and greatly expedite the manufacture of such devices. Thus the acts of putting glue spots on the cord, of applying beads to glue spots, of burnishing formed beads, of cooling the beaded cord and of dipping the same in a solution can be preformed at the same time. Further, the process is a continuous one in that there is constant travel of the cord while the different operations are preformed. While the driving mechanisms for the diiferent elements are not illustrated in the'drawing, any suitable driving means may be used.

' I am aware that changes may be made in this process and the steps thereof without departing from the principles of this invention, so I do not propose limiting the patent granted thereon otherwise than necessitated by the appended claims.
